A spokeswoman for Robinson Cano's RC24 Foundation has ties to a Miami anti-aging clinic under investigation by Major League Baseball, according to ESPN.com.

A client list obtained by the website showed that, last July and August, Sonia Cruz visited Biogenesis, a clinic under investigation from MLB to determine whether it supplied performance-enhancing drugs to major- and minor-league ballplayers.

Melky Cabrera, the Toronto Blue Jays outfielder and a good friend of Cano, and Alex Rodriguez, the Yankees third baseman who has mentored Cano, have both been tied to Biogenesis. Francisco Cervelli, the Yankees catcher, has also been tied to the clinic.

MLB told ESPN it is investigating whether Cano, 31, has any direct ties to the clinic.
